From humberto at hpcf.upr.edu Sun Sep 19 10:58:35 2004 From: humberto at hpcf.upr.edu (Humberto Ortiz Zuazaga) Date: Sun, 19 Sep 2004 10:58:35 -0400 Subject: [Internet2] Internet2 forms part of a large scientific instrument. Message-ID: <200409191458.i8JEwZqj025433@daleth.hpcf.upr.edu> The Internet2 allowed scientists to construct a transatlantic scientific instrument. The Arecibo Observatory and 3 other sites in Europe participated in an experiment where the 4 radiotelescopes were joined into an "electronic Very Long Baseline Interferometer" (eVLBI). The link is achieved by transmitting the data from the telescopes live over high-speed research networks to a central processing station in Europe. >From the eVLBI news: "eVLBI research achieved another first on Friday 10th September when real-time fringes were detected between the 305m Arecibo radio telescope and three antennas located in Europe." Pictures and more information at the eVLBI site: http://www.evlbi.org/evlbi/te024/te024.html During the experiment, 32 Mbps (millions of bits per second, approximately 21 T1 lines or 600 times faster than dial up modems) of data were transmitted from each of the telescopes to a processing center in the Netherlands, where the results were analyzed live. Press releases of an earlier experiment are also available: http://www.jive.nl/docs/pr/pr_realtime.html -- Humberto Ortiz Zuazaga Programmer-Archaeologist High Performance Computing facility University of Puerto Rico http://www.hpcf.upr.edu/~humberto/ From jconde at rcm.upr.edu Mon Sep 20 07:57:13 2004 From: jconde at rcm.upr.edu (=?ISO-8859-1?Q?=22Jos=E9_G=2E_Conde=22?=) Date: Mon, 20 Sep 2004 07:57:13 -0400 Subject: [Internet2] Re: [sysadmin] Internet2 forms part of a large scientific instrument.
